20 Claims, 9 Drawing Figures SHEET an Ki FROM VOLTAGE SOUQCE COMPRESSED NRVACUUM SOURCE FROM vome'e $OURCE VOLTAGE SOURCE COUNTER SED SEQUENCE OPERATOR NR $OURCE FROM COMPKES FIELD OF THE INVENTION The present invention relates to handling of hosiery during the manufacturing process, and more particularly, to an improved arrangement wherein the individual hose are turned, separated from the string, pulled off the turning form and stacked.

BACKGROUND OF THE INVENTION During the manufacture of hosiery, particularly socks, it is common practice to knit the hosiery in a continuous elongated tube. Periodically, this tube or string of hosiery is removed from the output container of the knitting machine for further processing into a finished product. The individual hose of the string of hosiery is connected to the string by a knitted ring of break-away thread. This facilitates the separation of each hose in turn, that is required before the further processing can proceed. This preliminary manipulative or handling step has typically been performed by simply grasping the first in-line hose in one hand and the remainder of the string in the other, and pulling the two apart.

The next processing step to be performed on the hose, that is, after being separated from the string, is the sewing or closing of the toe. However, since the hose is usually knitted in the right side-out condition, it is required that the hose at the time of separation also be turned inside-out for the seamstress. Thus, heretofore, the preliminary everting operation has been typically performed by hand just after the manual separation step, and is usually performed by this same operator. The everted hose are counted and stacked by hand to complete the preliminary handling steps prior to delivery to the seamstress.

The performance of these preliminary handling tasks by hand is an extremely tedious and slow process. Furthermore, operating on the string of hose by hand greatly limits the number of hose on a string that can be conveniently handled at one time. That is, the strings have been required to be relatively short in order to be manageable. This causes additional time loss as more handling is naturally required to manipulate the extra number of strings. Also, even with the short lengths, this preliminary separating, turning and stacking process is likely to result in inadvertent soiling of the hosiery or a snagging of threads by the operator. Finally, manual handling as described can result in occasional failure to turn or completely turn the hose, as well as result in failure to form a neat stack required for efficient toe closing.

Heretofore, it has been proposed to provide a form to assist in this manual operation. Essentially, the form serves merely as a substitute for the persons arm that is performing the manual turning. One such proposed form is shown in British Patent No. 784,206, issued Oct. 2, I957. This form, while possibly relieving the operators arm from considerable irritation caused by repeated pulling of a string of hose over the same, has failed to gain acceptance in the hosiery manufacturing field. I conclude this is so mainly due to the failure to make any significant improvement in terms of speed of operation; and indeed using this prior form probably slows the operation. Furthermore, the prior art form fails in reducing the harmful effects of manual handling since it is still necessary to grip the socks with the fingers of the hands to pull the hose apart from the string and to pull the same off the form over the end collar. The counting and stacking, of course, must still be done manually in accordance with this prior art teaching.

OBJECTS OF THE INVENTION Thus, it is a main object of the present invention to provide a semi-automatic method and apparatus for turning and separating hosiery that overcomes the aforementioned objections of manual handling.

It is a related object of the present invention to provide an arrangement for turning and separating hosiery where the only manual handling is sliding the hose along a tube.

It is still another object of the present invention to provide a method and apparatus for l turning a hose in a vacuum tube, (2) separating the hose after turning by engagement of a double over portion, and (3) counting and/or depositing the hose in a stack for further processing.

It is still another object ofthe present invention to provide a method and apparatus of handling hose wherein the preliminary separating function is performed simultaneously with the pulling of the hose off a vacuum tube in which the hose has been turned.

It is another object of the present invention to provide a turning, separating, counting and/or stacking arrangement that operates at a speed substantially above the speed of manual operation previously attained, with or without a solid form of the prior art.

BRIEF DESCRIPTION OF THE INVENTION A new method of efficiently handling hosiery comprises the steps of placing a string of hose on a hollow form, inducing ingress of air through the open end of the form, moving the string to draw the hose into the form to evert or turn the hose, holding a portion of the hose adjacent the open end, separating the hose and pulling the hose off the form to move the same to a stacking station. The hose is doubled-over on itself at the open end of the tube for easier grasping by the pulling and stacking arm. The hose making up the string are interconnected to each other by a knitted ring of polyester yarn having a low tensile strength, such as Alignate yarn. The separating step is advantageously performed simultaneously with the pulling-off step by manually holding the string and allowing the pull on the hose to break this connector ring.

As the hose moves off the end of the form it is delivered in the same motion over a stacking station and released, forming a stack ready for tying after a predetermined number have been stacked.

A string is placed on the form by pulling-on over the open end of the form and bunching the string toward the opposite end. In accordance with another feature of the invention, this step is performed while inducing egress of air from the open end to preopen the string and reduce the frictional resistance. An endless moving surface, such as a power driven roller, may be utilized to engage the string during the pulling-on operation for additional assist.

The apparatus for pulling-off the hose from the string comprises a pair of fingers adapted to be positioned on opposite sides of a flattened side of the mouth of the form. One finger extends into the mouth of the form with the other finger on the outside. The hose is stopped short of a full turn so that a doubled-over portion of the hose is thereby gripped. The fingers are carried on an oscillating arm that moves in an are from the position where the hose is pulled off the form and free of the string to the stacking station. The end of the form is flattened in this area to assure a secure grip on the hose.

The finger extending inside the tube moves toward the finger on the outside, which is in fact formed by the end of the oscillating arm. A spring loaded over-center linkage operates and holds the fingers in the gripped position. A first stop at the limit of travel toward the form operates the linkage to grip the hose. and a second stop provides the release at the other extreme of travel adjacent the stacking station. Bumpers are provided to cause the operating lever of the over-center linkage to be urged by momentum in the proper direction to assist the tripping operation.

The spring of the over-center linkage is attached at one end to the arm and at the other end to the operating lever so that said spring passes over the pivot point of the lever between the gripping and releasing positions. A crank and slide are used to operate the finger extending inside the tube from the operating lever.

Still other objects and advantages of the present invention will become readily apparent to those skilled in the art from the following detailed description, wherein I have shown and described only the preferred embodiment of the invention, simply by way of illustration of the best mode contemplated by me of carrying out my invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to FIGS. 1 and 2 of the drawings, there is shown a preferred embodiment of an apparatus for turning, separating and stacking hose in accordance with the principles of the present invention. Specifically, a turning, pulling and stacking apparatus, generally designated by the reference numeral 10 is illustrated mounted on a work table T. The apparatus in cludes a hollow tubular form II pivotally mounted on the table T by a suitable pivot stand I2 (see FIG. 3). An oscillating arm 13 of the apparatus I0 is pivotally mounted on a similar stand 14 (see FIG. 2a) with a pivot pin 15. A pneumatic cylinder I6 is pivotally attached to one end of the arm 13 to oscillate the same about the pivot pin 15. A hose grasping means, gener ally designated by the reference numeral 17, is carried on the opposite end of the arm 13. The grasping means include two opposed fingers 17a, 17b and these move along the arcuate delivery path P. as shown best in FIG. 1. As will be seen later in detail, the arm 13 moves during the operation between extreme limit positions of the full line position of FIG. 1 and the full line position of FIG. 2.

With reference to FIG. 3, there is shown a string of hose S as is being initially preloaded onto the tubular form 11. The string S is made up of a plurality of individual hose or socks s s s s.,...s, connected by connector rings r, r r r.,...r, of Alginate yarn. The tubular form 11 during this handling step has actually been bodily pivoted on the stand 12 to the dotted line loading position of FIG. 2.

In this preliminary operation, one end of the string S is placed on the form 11 and pulled up to a point where roller 20 rotated by a motor 21 may engage the string S. The form is moved down into the roller 20, and with the inside of the tube serving as a back-up to the endless moving driving surface, the string S is rapidly moved onto the form. The tube is tightly bunched at the end, as shown in FIG. 3, so that a relatively long string may be accommodated. As the string clears the roller the feeding stops and the tube It is lifted and pivoted in the direction of the arrow in F IG. 2, in readiness for the next handling step.

A suitable switch 22 (FIG. 3), that may be a foot operated switch or a position sensitive switch mounted on stand 12, supplies current to the motor 21 from a suitable voltage source, as will be described later. Once the string S is on the tube 11 and the first in-line sock s, is moved forward adjacent mouth Ila (FIGS. 4 and 4a) of the tube 11 (FIG. 4), the pulling operation in accordance with the present invention is ready to begin, as will momentarily be described.

The open mouth 11a is provided with a flattened side 1 lb, as best shown in FIG. 2b. This flattened side is provided to present a surface that can be best engaged by the fingers 17a, 17b of the grasping means 17. The doubled-over portion of the sock is held flat so that the fingers 53, 54 securely grasp the sock. As the sock is pulled free of the flattened side Ilb, the fingers 53, 54 close more completely to grasp the double thickness of the sock and assure the sock is not dropped during the travel along the path P.

In order to operate to load the string S and to turn the hose first in-line on the string S on the hollow tubular form 11, a pneumatic feed tube 25 is connected to the form (see FIG. 3). A two-way valve 26 provides either compressed air or vacuum from the source 27 through the connections 28, 29, respectively. The valve 26 is operated by a second switch 30 (either foot-operated or form II position responsive) that is provided current from the voltage source as best shown in FIG. 3.

Supplying the compressed air through the valve 26 and out the mouth 1 la of form 1 l is of considerable advantage in the present invention (as best shown in FIG. 3) since the air egressing from the open mouth causes the hose just beyond the end, such as hose s, of the string S, to be temporarily streteched outwardly. This preopens the string S to reduce the frictional resistance at the open mouth 1 la of the tube and greatly enhances the speed and efficiency of loading operations. With the combined blowing of air and the rotating roller to assist in moving the string 8 onto the tube 11, the operator is able to load a full string of socks in a very short time.

When the entire string S has been loaded, the form 11 is bodily pivoted from the dotted line position of FIG. 2 to approach the full-line position of FIG. 1. The movement of the tube 11 toward the full-line position operates the switch 30 to change the valve 26 for connection to the vacuum side of source 27 so that ingress of air through the open mouth 11a begins. The operator with his hand H, as shown in FIG. 4a, simultaneously moves the first sock s, toward the open mouth. The hose or sock s, is drawn into the open end of the tube as the hand continues to move, as shown in FIG. 4b.

The sucking of the hose s, into the form 11 does of course effect a turning. When the position of FIG. 2 is reached, a substantial full turn of sock s, is complete with the majority of the sock being inside the form 11. The connector ring r, attaching the hose s, to the hose s is stopped just short of the open mouth 11a. A doubled-over portion, preferably the welt end, is now positioned in readiness to be gripped across the flattened side 11b of form 11 by the grasping fingers 17a, 17b. The operator pivots the form 11 inward the final distance against the positioning stop 35. This aligns fiattened side 11b of the tube 11 with the open grasping means 17 (compare FIGS. 1 and 2). In this operative position, the form hits and closes switch 36 (see FIG. 2). The cylinder 16 is activated sweeping the arm 13 along path P of FIG. 1. In FIG. 2, the arm has reached the extreme inward position and the grasping fingers 17a, 17b are just ready to close on the doubled-over portion of the sock s,.

In FIG. 4, the fingers 17a, 17b (dotted line outline) have closed and the arm has reversed, breaking the connector ring r, and pulling the sock s out of the open mouth 11a of the form 11 in the everted position. The arm 13 moves the hose s, along the predetermined path P to the dotted line position of FIG. 2. The hose is counted and is dropped in a stack on a suitable tray 40, which stack when complete is ready to be tied by a suitable tie t into a bundle ready to be transferred to the seaming station for closing of the toes.

From just the foregoing and before discussing in more detail the particular apparatus and control, it can be realized that the method operation of the present invention is advantageously simple and capable of rapid and efficient execution. All the operator needs to do is load the string S and then move by a gentle sliding motion each succeeding sock s s ...s, toward the open mouth of the form for turning. He stops and holds the doubled-over portion of each sock adjacent the open mouth. The grasping means 17 on the end of the arm 13 engages and securely grips the doubled-over portion of each sock, as shown in FIG. 2, and then pulls the socks in turn off the tube, simultaneously separating each connector ring n, r,...r,. In the same motion. each sock is moved along the delivery path P to the stacking station on the tray 40 where the bundle is formed.

With reference now to FIGS. 2 and 2a, the arm I3 is provided with a bolt 45 having a lock-nut for mounting a pivotal operating lever 47 of an over-center mechanism, generally designated by the reference numeral 48. The lever 47 is raised from the surface of the arm 13 by a U-shaped support and ring 49. A laterally extending crank 50 is mounted on the pivot bolt 45 for movement with the lever 47. The crank 50 in turn moves a slide 51 held on the arm 13 by a yoke 52 (see FIG. 2). The end of the slide 51 is turned and bent over and provided with a resilient pad to form the moving finger 17a of the grasping means 17. The other finger 17b of the grasping means 17 may be formed by a similar resilient pad mounted on the terminal end of the arm 13.

A spring 55 has one end attached to the arm 13 adjacent the pivot pin 15 (see FIG. I and FIG. 2) with the other end attached to a lateral extension 56 of the operating lever 47 of the over-center mechanism 48. When operating lever 47 is in the position shown in FIG. 2, the spring 55 has moved to the right in the Figure over the pivot point at the bolt 45. This means that the crank 50 is biased counterclockwise (note arrow in FIG. 2) so as to hold the two fingers 17a, 17b firmly together against the doubled-over end portion of the hose 5,. The arm 13 is then moved so as to pull or withdraw the hose s, from the form 11. The fingers grip and hold sufficiently firm to breakaway the connector ring so that the sock is separated in the same withdrawing motion, as desired.

As the dotted line position of FIG. 2 is reached, a first stop 60, stationarily mounted on the table T, engages the operating lever 47 and trips the mechanism 48. The lever turns clockwise about the pivot bolt 45 and the spring moves over-center causing the crank 50 to likewise move clockwise (note dotted line arrow in FIG. 2). Almost simultaneously, a first bumper 61 is engaged by a projecting member 62 on the arm 13 so that momentum of the bodily moving lever 47 with the extension 56 assures the proper movement of the crank 50 and the opening of the fingers 17a, 17b. The opening of the fingers 17a, 17b drops the sock s, on the stack and the next sock s is then ready to be turned and pulled.

A second stop 65 engages the operating lever 47 to push the lever and trip the same for the closing action, as previously described (see dotted line position of FIG. 1). A second bumper 66 serves to abruptly stop the arm 13 in just the right position for the fingers 53, 54 to engage the doubled-over portion of the sock. As before, the stopping action causes the momentum of the arm 47 to make certain that over-center travel of the spring 55 is effected, as clearly shown by comparison of the dotted line position of FIG. 1 to the full line position of FIG. 2.

In FIG. 5, there is shown atypical control circuit that may be utilized with the apparatus 10 of the present invention. A voltage source 70, such as ll0-volt AC, is

provided. This same source may also provide the power for the operation of the motor 21 and of valve 26 (FIG. 3), described above. A sequence operator 71 is shown to depict a suitable electrically operated switch-valve combination to supply compressed air from the source 27 to the operating cylinder I6 in the sequence desired. A counter 72 registers each cycle and thus each hose that is placed in the stack. The switch 36 controlling the combination is operated by the finger of the operator as the form 11 is brought into an operative position for the separating function, as previously described.

Briefly summarizing, it can be seen from the above description that an improved method and apparatus for turning, separating and stacking hose, all in one handling operation, has been provided. First, a string of hose taken directly from the knitting machine is pulled onto a hollow tubular form aided by preopening action on the string S by induced flow of air from the open mouth 11a of the form and by a rotating wheel 20. After the string S has been loaded on the form 11, it is pivoted from the dotted-line position of FIG. 2 toward the full-line position. Prior to engaging the limit stop 35 by the side of the form, the switch 30 switches the valve 26 to provide a vacuum in the form reversing the flow thereby inducing ingress of air through the open end. The operator slides his hand H forward, as shown in FIG. 4a, continuing until the first hose s, is drawn into the open mouth and turned (FIG. 4b). The operator stops and holds the string when the doubled-over portion of the sock s, remains outside the form 11, as shown in FIG. 2. The form 11 is moved the short distance into abutment with stop with the flattened side 11b aligned with the path of the grasping fingers 17a, 17b (FIG. 2). The operator in the same motion activates the switch 36 causing the sequencing of the apparatus 10. With one rapid, full cycle oscillating motion of arm 13, the first sock s, is grasped, separated and pulled off, (FIG. 4) and stacked (FIG. 2). Each sock s s ...s in turn, is rapidly handled by the simple, short in and out motion of the form 11 (see FIG. I) and the concurrent sliding of the string S forward (FIGS. 4a and 4b).

In this disclosure. there is shown and described only the preferred embodiment of the invention, but, as aforementioned, it is to be understood that the invention is capable of use in various other combinations and environments and is capable of changes or modifications within the scope of the inventive concept as expressed herein.
